The YETI Rambler 36oz Bottle is designed for a life in the wild. Scorching days on the ranch and getting dropped on rough terrain are this bottle’s calling, second only to keeping your drinks icy cold, or perfectly hot. YETI uses durable, kitchen-grade 18/8 stainless steel with No Sweat Design. This means your Rambler® resists dents, dings, and condensation, while keeping your drinks just how you like them.
